Chapter 1 1. Advantages of bursty data communication a Pulses are made very narrow, so multipaths are resolvable b The transmission device needs to be switched on for less time.
Disadvantages a Bandwidth required is very high b Peak transmit power can be very high. Sandeep Sachan. Nelson Martin Vizcaino Ceresa. Mujtaba Mirza. Yina Bai. Edson Silva. Sourav Mondal.

The transportation cost is very high each time. However, if the infrastructure is set once, it will be very easy to use it repeatedly. Time for wireless transmission is negligible as signals travel at the speed of light.
Advantages of bursty data communication a Pulses are made very narrow, so multipaths are resolvable b The transmission device needs to be switched on for less time. Disadvantages a Bandwidth required is very high b Peak transmit power can be very high. Inter-cell interference is very high and should be mitigated to get reasonable SINR. Infrastructure cost is another problem. Smaller the reuse distance, larger the number of users who can use the same system resource and so capacity data rate per unit bandwidth increases.
One CDPD line : Chapter 2 1. Also, shadowing is less due to fewer obstacles. Also note that the the received power actually increases with distance up to some point. This is because for very small distances i. Piecewise linear model for 2-path model. See Fig 2 Outage Prob. In this way the probability of power outage will be less because both base stations are unlikely to experience an outage at the same time, if they are uncorrelated.
Chapter 3 1. Use CDF strategy. This is seen from the tail behavior of the two distributions in their pdf, where the tail of Nakagami-distribution is always above the Ricean distribution. Conclusion : Independent shadowing is prefarable for diversity. There are many acceptable techniques for this problem. Can also just do a Rayleigh distribution with an adequate LPF, although the above technique is prefered.
In the reader, we found the level crossing rate below a level by taking an average of the number of times the level was crossed over a large period of time. It is easy to convince that the level crossing rate above a level will have the same expression as eq. Notice that as fD increases, tZ above reduces. So, if we choose our data rate such that a single symbol spans the average fade duration, in the worst case two symbols will span the fade duration.
So our code can correct for the lost symbols and we will have error-free transmission. Selective Manage consent.
